The store manager of a local independent grocery store thought customers might stay in the store longer if slow, easy-to-listen-to music were played over the store's intercom system.
After some thought, the manager considered whether he should hire a marketing researcher to design an experiment to test the influence of music tempo on shoppers' behaviors. Answer the following questions:
a. How would you operationalize the independent variable?
b. What dependent variables do you think might be important in this experiment?
c. Develop a hypothesis for each of your dependent variables.
